You are asking questions that I would have known 40 years ago☺ but the answer is both yes and no. It depends on the pump type and my dim memory says that a vane pump you can adjust the out put by the speed. The gear pump is designed to work best one general speed

You do intend to buy a new pump? You will find the required RPM and all other specs at the dealers website

Either pump you have mentioned will work, neither pump will overheat your oil. Tank size should be at least the pumps output
